style="font-size:16px;">固定球閥的特點1、雙阻塞與排放功能：固定球閥采用彈簧預(yù)緊浮動閥座，無論閥門處于全開或全關(guān)狀態(tài)時，上下游側(cè)的閥座使流體阻斷，閥體中腔滯留物通過排放閥排泄。2、自動泄壓功能：閥門體腔停留介質(zhì)溫度升高而引起異常升壓時，不需通過安全閥，而*靠閥座功能就可自動泄壓，這對保證閥門在輸送液體介質(zhì)時的安全性非常重要。3、防火安全結(jié)構(gòu)：閥門都具備防火安全功能，其設(shè)計、制造均遵循API607和API6FA規(guī)范要求。固定球閥的優(yōu)勢1、密封緊急注脂救護：由于介質(zhì)中的異物或火災(zāi)造成閥座密封意外失效，注脂閥提供了與注脂的快速連接，方便快捷地將密封脂注入到閥座密封部位，緩解泄漏。2、可靠的閥桿密封和低操作力矩：除了設(shè)置標準密封套圈外，填料壓蓋上也設(shè)置了“O”型密封圈，雙重密封保證了閥桿密封的可靠性；增設(shè)的石墨填料和密封脂注入使火災(zāi)后的閥桿泄漏降至比較低。閥桿滑動軸承和止推軸承使閥門操作輕便。3、全通徑或縮徑：可根據(jù)需要選用全通徑或縮徑結(jié)構(gòu)。</span><span

style="font-size:16px;">由于球閥通常用橡膠、尼龍和聚四氟乙烯作為閥座密封圈材料，因此它的使用溫度受到閥座密封圈材料的限制。球閥主要的閥座密封圈材料就是聚四氟乙烯（PTFE），它對幾乎所有的化學(xué)物質(zhì)都是惰性的，且具有摩擦系數(shù)小、性能穩(wěn)定、不易老化、溫度適用范圍廣和密封性能優(yōu)良的綜合性特點。但聚四氟乙烯的物理特性，包括較高的膨脹系數(shù)，對冷流的敏感性和不良的熱傳導(dǎo)性，要求閥座密封的設(shè)計必須圍繞這些特性進行。閥座密封的塑性材料也包括填充聚四氟乙烯、尼龍和其他許多材料。但是，當(dāng)密封材料變硬時，密封的可靠性就要受到破壞，特別是在低壓差的情況下。此外，像丁青橡膠這樣的合成橡膠也可用作閥座密封材料，但它所適用的介質(zhì)和使用的溫度范圍藥受到限制。另外，如果介質(zhì)不潤滑，使用合成橡膠容易卡住球</span><span

<span
